'hdparm -I' doesn't work with ATAPI devices and sg_sat is not widely spread yet leaving no easy way to access ATAPI IDENTIFY data. Implement HDIO_GET_IDENTITY such that at least 'hdparm -i' works.
Mmm.. I still think this old ioctl is ugly, and I'd rather have things fixed so that "hdparm -I" works instead. Unless having access to the libata cached ID block is useful beyond just getting ATAPI drives to work with -I. Is it? I suppose it might be useful to be able to look at it. hdparm *does* try to issue the PACKET IDENTIFY whenever a regular IDENTIFY fails. Currently these all go through the HDIO_DRIVE_CMD ioctl(). I don't have a system set up here that has any ATAPI over libata to test with. Could you perhaps try and see where that ioctl() is failing?
